HOlSTlNG MECHANISM FOR PORTABLE'ORTRACTION ENGINES.

SPECIFICATION forming part of Letters Patent No. 721,001, dated.February 17, 1903. Application filed July 3, 1902. Serial No- 114,29r.on model.)

To all whom it may concern:

Be it known that I, FRITZ BENDER, a citizen of the United States,residing at Littlerock, in the county of Saline and State of Missouri,have invented certain new and useful Improvements in Hoisting Mechanismfor Portable or Traction Engines, of which'the following is aspecification.

This invention provides simple, effective, and novel mechanism forelevating a portable or traction engine for any desired purpose, thismechanism being applied to the engine and adapted for use at a momentsnotice for raising or lowering the engine, as may be required, thehoisting mechanism being readily operable by means of the engine oradapted to be operated independent of said engine.

The primary object of the invention is to lessen the labor and obviatethe loss of time usually resulting when loading the engine upon a truckor unloading it from said truck after reaching a destined place of, use.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreifecting the result reference is to be had to the following descriptionand drawings hereto attached. 7

While the essential and characteristic features of the invention aresusceptible of modification, still the preferred embodiment of theinvention is illustrated in the accompanying drawings, in which Figure lis a side elevation of a tractionengiue embodying the invention. Fig. 2is an end view of the engine as seen from the front. Fig. 3 is aperspective View of the hoisting mechanism disassociated from theengine.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The engine illustrated may be of any type and has been selected simplyto illustrate the application of the invention, which resides in the lifting or hoisting mechanism comprising the elements hereinafter referredto in detail.

Lifting-bars 1 are located at the sides of the engine and are mounted insuitable guides 2 and are provided at their lower ends with shoes 3 toobtain a firm bearing upon the ground, plate, or block. Each lifting-baris provided at one of its vertical edges with cogs or teeth 4, formingsegments of a thread or spiral and in mesh with a worm-pinion 5, securedto the lower end of a vertical shaft 6. The upperend of each shaft 6 isprovided with a pinion 7 in mesh with a worm 8, applied to a transverseshaft 9, journaled in bearings applied to the engine and provided at oneend with a belt-pulley 10, adapted to be 0perated from the engine or tobe moved by hand, as desired. The shafts 6 and 9 are convenientlydisposed according to the design or type of engine provided with theinvenr-ion, and by having both shafts 6 geared to the shaft 9 and to thelifting-bars 1 the latter are simultaneously operated, thereby liftingboth sides of the machine alike, provided the ground is level or theshoes of the lifting-bars are properly. blocked.

In the event of it'being desired to operate the hoisting mechanism fromthe engine a drive-belt 11 connects the pulley 10 with the fly-wheelorrband-pnlley 12 of the shaft 13, connected for operation by means ofthe engine in any accustomed way. The pulley 10 being connected to thepulley 12 in the manner stated and the engine operated, the lifting-barsl are moved vertically downward to lift the engine and upward to lowerthe engine, as will be readily comprehended. The lifting-bars maybelocated at any conyenient position; preferably near the front and at thesides of the fire-box, thereby enabling the shaft 9 to extend across thefront of the engine, as indicated in Fig. 1.

Having thus described the invention, what is claimed as new is-- 1. Inan engine of the portable or traction type, hoisting mechanism appliedthereto and comprising lifting-bars mounted in vertical guides appliedto opposite sides of the engine and having corresponding vertical edgesprovided with cog-teeth, vertical shafts, worm pinions applied to saidshafts and in mesh with the cog-teeth of the lifting-bars, and atransverse shaft geared to each of the vertical shafts for simultaneousactuation thereof, substantially as set forth.

2. In combination with a portable tractionengine, vertical guidesapplied to the sides thereof, lifting-bars mounted in said guides andhaving vertical edges provided with cogteeth, vertical shafts,worm-pinions secured to the said shaft and in mesh with the cogteeth ofthe lifting-bars, a transverse shaft, s

and worm-gearing between the transverse shaft and each of the saidvertical shafts, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
